You did not recognize him, perhaps, because Phillip Mius was not actually a D'Entremont His father, Claude Antoine de Meuillon Mius, was brought up by the d'Entremont family after his father was killed in The Saint Bartholomew Day Massacre of Huguenots. Phillip assumed the D'Entremont name. Two of Phillips sons refused to use the d'Entremont name and by official documents reverted to the surname Mius. The rest of the family continued with D'Entremont. Thus, you have the two surnames still used today evolving from a common ancestor. Both families have thrived and today many can be found in South West Nova Scotia.
